Update framework7-vue version inside package.json

[centrual]

Hello,

In package.json Framework7-Vue version is 0.7.0 and it throws errors like

[Vue warn]: existing instance property "dividerOrGroupTitle" will be overwritten by a computed property with the same name. 
(found in component <f7-list-item>)

please update to 0.7.2 for fix.

Note: Npm doesn't contains 0.7.2 version currently. Because of that, you need to update framework7-vue dependency to https://github.com/nolimits4web/Framework7-Vue-Webpack-Template.git manually.

Added package.json change to #6
Please check template folder.
